Read captions from IPTC info

I use Lightroom for managing my photos, and it embeds IPTC captions in exported JPEGs. Many services like Google Plus and Flickr automatically pull from these captions; can you do the same with Lifecake?

This would be a huge improvement for some of us. I just started investigating lifecake as a backup and a replacement for managing our own site and not pulling existing IPTC data essentially means I'd have to type everything twice.
